GE WR55X10942 Refrigerator Main Control Board, green, 7.40 x 2.70 x 11.20 inches

A constant clicking from the motherboard indicates a bad board. A bad motherboard may show burnt marks or bad soldering joints from overheating on the front or back of the board. If the refrigerator lights dim when you get ice/water, or if the ice melts and refreezes are also signs of a bad motherboard. A hum and then a click a few seconds later from the compressor indicates a compressor or relay issue but not a motherboard problem.
